OUTCOMES FOR CATHETER ABLATION OF ANTEROSEPTAL AND MIDSEPTAL ACCESSORY PATHWAYS IN PEDIATRIC PATIENTS.

Ablation of AS and MS pathways remains challenging. Multiple approaches are often necessary to successfully ablate AS pathways. While both ablation energy modalities were equally successful, cryoablation may be associated with a higher chance of recurrence. Recurrences and repeated procedures may be anticipated to minimize risk to normal AV conduction during ablation in these regions.
